A case study of CIP tails slurry treatment: comparison of ...

2015-12-27  In this paper two cyanide recovery/destruction technologies, namely the Cyanisorb process and the INCO SO2/Air process, are evaluated for the treatment of waste cyanide effluents from a gold mill of 12,000 tonnes of ore per day capacity. The comparison is made for CIP tails slurry of variable concentrations of free and weakly-complexed cyanide.
